The main objectives of this project are to lower carbon emissions and improve the dependability of integrating renewable energy sources into the PLN electrical system by optimizing a 1.35 MW grid-connected solar power plant (PLTS) in Demak, Central Java. Hourly solar irradiation and generation data collected over the course of a year were used to evaluate the plant's performance. The results showed an annual energy production of about 88.94 MWh, or a 20% capacity factor. The PLTS is positioned as a major contribution to Indonesia's decarbonization program under the Paris Agreement because of this output, which allows an anticipated reduction of 71.15 tons of CO2 emissions annually. Three specific optimization techniques are suggested by the study to address issues relating to solar energy's sporadic nature. In order to store excess energy during periods of high production and deliver it during periods of low generation, it is first recommended to integrate lithium-ion battery storage systems, which have a round-trip efficiency of over 90%. In order to improve supply and demand alignment, demand-side management is used to move non-critical loads, especially in the commercial or industrial sectors, to daylight hours when solar generation is at its peak. Third, to improve the economic viability of solar energy investments and hasten adoption across areas, legislative tools like feed-in tariffs and net metering should be put into place. This study's focus on small-scale solar systems linked to the national grid and its realistic modeling approach utilizing actual data are what make it novel. Strong empirical support is provided by the results, which show that grid-connected PLTS can enhance energy security, drastically cut greenhouse gas emissions, and provide reproducible models for comparable areas. For stakeholders, legislators, and energy planners looking to improve the use of renewable energy sources and achieve national sustainability goals through focused technology and legislative interventions, this document provides insightful information overall. © Published under licence by IOP Publishing Ltd.
